HEADLAMP (XENON)

HEADLAMP (XENON) : Description

INFOID:0000000001527568

The IPDM E/R (intelligent power distribution module engine room) controls the headlamp low relay based on
inputs from the BCM via the CAN communication lines. When the headlamp low relay is energized, power
flows through fuses 40 and 41, located in the IPDM E/R. Power then flows to the front combination lamps to
the headlamp low beam.

HEADLAMP (XENON) : Component Function Check

INFOID:0000000001527569

1.

CHECK HEADLAMP (LO) OPERATION

WITHOUT CONSULT-III

1.

Start IPDM E/R auto active test. Refer to 

XX-XX, "*****"

.

2.

Check that the headlamp is turned ON.
NOTE:
HI/LO is repeated 1 second each when using the IPDM E/R auto active test.

CONSULT-III

1.

Select "EXTERNAL LAMP" of IPDM E/R active test item.

2.

With operating the test items, check that the headlamp is turned ON.

Is the headlamp turned ON?

YES

>> Headlamp (LO) is normal.

NO

>> Refer to 

EXL-39, "HEADLAMP (XENON) : Diagnosis Procedure"

HEADLAMP (XENON) : Diagnosis Procedure

INFOID:0000000001527570

1.

CHECK HEADLAMP (LO) FUSES

1.

Turn the ignition switch OFF.

2.

Check that the following fuses are not open.

Is the fuse open?

YES

>> Repair the harness and replace the fuse.

NO

>> GO TO 2

2.

CHECK HEADLAMP (LO) OUTPUT VOLTAGE

CONSULT-III

1.

Turn the ignition switch OFF.

2.

Disconnect the front combination lamp connector.

3.

Turn the ignition switch ON.

4.

Select "EXTERNAL LAMP" of IPDM E/R active test item.

5.

With EXTERNAL LAMP ON, check the voltage between the combination lamp connector and ground.

Is the measurement value normal?

YES

>> GO TO 4

NO

>> GO TO 3

3.

CHECK HEADLAMP (LO) CIRCUIT FOR OPEN

1.

Turn the ignition switch OFF.

2.

Disconnect IPDM E/R connector.

3.

Check continuity between the IPDM E/R harness connector and the front combination lamp harness con-
nector.

Does continuity exist?

YES

>> GO TO 4

NO

>> Repair the harnesses or connectors.

4.

CHECK HEADLAMP (LO) GROUND CIRCUIT

1.

Disconnect the front combination lamp connector.

2.

Check continuity between the front combination lamp harness connector terminal and ground.

Does continuity exist?

YES

>> Inspect the headlamp bulb.

FRONT FOG LAMP CIRCUIT

Description

INFOID:0000000001523265

The IPDM E/R (intelligent power distribution module engine room) controls the front fog lamp relay based on
inputs from the BCM via the CAN communication lines. When the front fog lamp relay is energized, power
flows from the front fog lamp relay to fuse 56 in the IPDM E/R and on to the front fog lamps. 

Component Function Check

INFOID:0000000001523266

1.

CHECK FRONT FOG LAMP OPERATION

CONSULT-III

1.

Select "FR FOG LAMP" of IPDM E/R EXTERNAL LAMPS active test item.

2.

With test items operating, check that the front fog lamps are turned ON.

Is the front fog lamp turned ON?

YES

>> Front fog lamp circuit is normal.

NO

>> Refer to 

EXL-41, "Diagnosis Procedure"

.

Is the fuse open?

YES

>> Repair the harness and replace the fuse.

NO

>> GO TO 2

2.

CHECK FRONT FOG LAMP OUTPUT VOLTAGE

CONSULT-III

1.

Turn the ignition switch OFF.

2.

Disconnect the front fog lamp connector.

3.
